Greenhouse Types

We stock our fantastic quality aluminium greenhouse range in various powder-coated colours, including black greenhouses, blue greenhouses, brown greenhouses, green greenhouses, grey greenhouses, silver greenhouses, white greenhouses, and red greenhouses. These can be used to either match your existing garden style with a sympathetic colour, or to create a bright and vibrant contrast with the surrounding garden, shrubs, lawn, and trees.

We also have traditional freestanding wooden glasshouses and potting sheds, both made with heavy-duty treated timber. These tend to be favoured by traditionalists, or those who prefer a natural look (although they tend to be more expensive than aluminium framed garden buildings or alternatives). Greenhouses are great alternatives to conservatories, polytunnels, or hothouses.

Greenhouse Categories

Popular greenhouse categories include:

Greenhouses, Glasshouses, Horticultural, and Polycarbonate Garden Greenhouse Options lets you customize your greenhouses online too, with glazing choices on the product page, including a choice of horticultural glass, toughened safety glass, or polycarbonate glazing. The glass options are ideal if you want a Victorian-style glasshouse that makes attractive garden buildings. Polycarbonate is best if you're concerned about safety, and horticultural glass is a compromise between style and safety (but is the most expensive option). Direct factory ordering for a great price and a simple shopping cart experience.

How To Choose a New Greenhouse

Greenhouses are a great way to extend the growing season and protect plants from extreme weather conditions. Here are some important features to consider:

  • You will need to consider factors such as location, size, materials used for construction, ventilation, and heating/cooling systems when building a glasshouse.
  • It is important to choose the right type of glazing material for your greenhouse in order to maximize light transmission and insulation.
  • Plants grown in greenhouses require more attention than those grown outdoors due to their increased vulnerability to pests and diseases.
  • You may be surprised at how quickly temperatures can rise inside a greenhouse on sunny days - it is important to ensure adequate ventilation is provided in order to prevent overheating, and use shading to protect sensitive produce from the hot summer sun. You may also need to water them more often, particularly if they're vegetables or herbs (especially tomatoes!).
  • Greenhouse gardening requires careful planning of crop rotation cycles in order to maintain soil fertility levels over time. They don't receive the renewal of soil like the natural environment does outside.

They can also be used to create ideal growing environments for specific types of plants and flowers, such as those that require higher humidity or more light than is available outdoors. 

Greenhouse Specifications

Here are the greenhouse specifications to look out for:

  1. Size: Length, width, and height of the greenhouse.
  2. Materials: Quality of materials used in construction.
  3. Type: Lean to greenhouses are installed against walls, whereas freestanding models can be located anywhere.
  4. Design: You can choose between standard models, victorian style models (which have large glazed panels), or dwarf wall models (which have a wall half way up the structure). Potting sheds are used to store tools and for growing plants.
  5. Ventilation: Number and size of vents for air circulation, including roof vents and auto vents or windows.
  6. Insulation: Level of insulation provided to maintain temperature control.
  7. Lighting: Type and amount of lighting available inside the greenhouse.
  8. Greenhouse Accessories: Shelving, benches, irrigation systems, etc., are they included with the purchase?
  9. Price/Value Ratio: Cost versus features offered by each model, which will vary depending on your needs.
  10. Doors: Consider which side of the greenhouse you need the doors to be, or if you will need more than one.
  11. Commercial or Domestic: If you have a commercial growing requirement, you will need a much larger greenhouse than most.
  12. Drainage: Consider how your growing areas within the greenhouse will have drainage, which is affected by the base you choose.

What is a Greenhouse?

Greenhouses are structures used for plant growth in a controlled environment, and they trap the warmth from the sun inside the structure to create a really good growing environment for plants and flowers. 

In the UK, they are typically used to protect plants from extreme weather conditions such as heavy rain or strong winds, although we do sometimes get hot weather in the summer! 

According to a report by Grand View Research, the global greenhouse market size was valued at USD 19.25 billion in 2020 and is expected to grow at a CAGR of 8.3% from 2021 to 2028 (source).

The UK Environment Secretary announced on 11th October 2022 they were committing to £12.5m in extra investment to encourage glasshouse growing (source).

Torn between a greenhouse or a shed?

It can be difficult to choose between buying a greenhouse and a shed, particularly if you can't prioritise between storage and growing space. In this situation, choose a wooden potting shed, as it's a combination of a shed and a greenhouse in one garden structure.

You have one glass side for horticultural work and gardening, and one solid side for storage of tools and machinery like lawnmowers. 

You still have glazing options (toughened glass or polycarbonate) with these structures, and they have the feeling of a conservatory, log cabin, or orangery, in that they are only partially glazed on one side. 

Incorporate lighting into the roof and add a desk if you want to work on weeding and planting later in the evening, and a heater if you plan to grow or plants seeds during the winter (the British winter weather is quite cold, so take a thermos of tea as well!). 

If you need more growing room, you can always bolster this with a cold frame on the patio.
